Size, specs & wrist fit compared

Which one fits you
On wrists narrower than about 46mm, the Active is the safer pick — it stays proportionate down to roughly 38mm, where the Active 2 starts to hang over the edge. Above 46mm both sit cleanly, and the Active 2 gives you more presence.
The Active 2 wears larger than the Active (43.9mm vs 42.36mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Active 2 is the slimmer of the two (9.9mm vs 10.75mm), so it slides under a cuff more easily.
On the wrist the Active feels lighter (27g vs 29.5g, case only).
The Active is thinner than 87% of the 42mm watches we track and the Active 2 than 99% of the 44mm ones — so both wear flatter than their widths suggest.
The Active 2 is 1.5mm wider, 8mm longer, 0.8mm thinner and 2.5g heavier than the Active.
